This afternoon using a Fubcube Dongle I detected the arissat-1 spectrum on 145.920 as the transmision doppled across. I've screendumped it as evidence! The signal was weak but visible (and audible) and rapid as you would expect at the nominal frequency. I used FCHiD to set the frequency and HDSDR to demod it at usb.
I owe it all to my homebrew one-transistor untuned preamp (RSGB's VHF-UHF handbook) at the end of a 6 ele XY fixed in az/el.
It didn't decode at the tlm software though, and I'll try again next weekend using DK3WN's doppler control software.
However I am pleased I have detected arissat1 bpsk with a FCD - that's one small step...
